On ibook, not only the usb devices (any mouse, DSL modem...) use a lot of energy, but they also use it when ibook is asleep ! My ibook can stay asleep for nearly a week with nothing plugged in, but it sucks all its battery in a night if I let the usb mouse. Now, I rmmod usb modules when sleeping, but I have not tested thoroughly if this reduce energy consomption. > >Bob Hentges >-- >http://bob.hentges.lu/ > > -- Cedric "[Of course] I'm French!
